MACHINE FoR FILLING AND SEWING SACKS. I

SPECIFICATION forming part of Letters Patent No. 562,438, dated June 23,1896.

Application filed March 15,1895, strain). 541,865. (NomodeL) To all whomit may concern: i

a citizen of the United States, residing in Ohicago, in the county ofCook and State of Illinois,have invented a new and useful Improvement inMachines for Filling and Sewing Sacks, of which the following is aspecification. I

My invention relates to improvements in machines for filling sacks orbags and sew ing up the mouths of the same after they are filled. 1 I lMy present invention is an improvement upon the sack filling and sewingmachine shown and described in my application, Serial No. 524,164.

My present improvement consists in combining with the series of sackholders, filling mechanism, and sewing device, an endless track alongwhich the sack-holders are conveyed first to the filling mechanism andthen to the sewing device, so that the holders are not discharged fromthe machine and do not require to be replaced in the machine.

It also consists in the combination of these parts with a device forautomatically printing desired marks or data upon the sack. In my newmachine I also convey the sack along solely by the holders, and thusmaterially simplify the machine by entirely dispensing with the carrierswhich I heretofore employed for supporting and carrying the sack.

It also consists in providing the track for the holder with a movablesection adapted to be vibrated up and down, and thus accomplishing theshaking of the sack from the holder, that is to say, from the mouth ortop taken together, are a side elevation of a ma- Y chine embodying myinvention. Be it known that I, ARTHUR T. TIMEWELL, 1

Fig.

M is the device for discharging and delivering the filled and sewedsacks from the machine.

The endless track B is furnished with flanges b b for the opposite sideedges of the holders D to fit against, so that the holders will beproperly guided in their path by these flanges of the track. The track Bhas a wide slot or open space 1) extending along that portion of thetrack at which the holder D is open, and a narrow slot b extending alongthat portion of the track where the sackholder is closed, and theguiding-flanges b b are brought close together at that portion of thetrack having the narrow slot 19 and where the holder is closed whenpassing along such portion. The track B is provided with suitablebridges B, spanning the slots 1) b at suitable intervals, so as toproperly support both sides or portions of the track. At the portion ofthe track B extending from the point where the filled and sewed sack isdischarged to the point where the empty sack is put into the holder theslot 1) or b is of course not necessary, and the two flanges orportions 1) b of the track may be here connected together by webs 5 Theendless conveyer C, by which the series of holders D are moved orconveyed along the track 13, consists, preferably, of a link-chaintraveling around the pulleys or sprocketwheels 0 C C O O C C, thesprocket-wheel C being the driving-wheel. The general path of theconveyer-chain O is along the inner guide-flange b of the track B, sothat the open links of the chain are adapted to engage the hooks d onthe inner sides of the holders D. At the place or portion of the track13 where the empty sacks are put into the holders the path of thisflexible conveyer C is deflected inward or away from the track of theholder, so that the holder will be thus automatically disengaged fromthe conveyer-chain and remain stationary on the track B while the sackis being put into the same; and, after the sack is placed in the holder,the holder is pushed by hand forward to that portion of the track wherethe conveyer-chain again meets it, and can thus again engage the hook dof the holder. The flexible conveyer-chain C is thus deflected at c awayfrom the track B by properly locating the guiding wheels or pulleys C Cof the chain. The path of the conveyer-chain C is also deflected inwardor away from the track 13 of the holder at the place a where the sack isto be filled and where the holder is stopped or remains sta tionary forthis purpose, so that at this time also the hook of the holder will bedisengaged from the conveyer 0, this second deflection of the conveyer 0being eflfected by the guide pulleys or wheels C For convenience andalso for the purpose of giving the holder a quicker movement from thefilling position to the holder-closing position, I preferably provide asupplemental conveyer-chain C, mounted on pulleys C 0 above the track B,

adapted to engage a movable or hinged hook I d on the holder and movethe holder forward to the position where the holder is closed.

The series of sack or bag holders D each consist, preferably, of sixhinged bars, the same comprising two opposite side or long bars d d andfour 'short or end bars 01 d 61 (1 All these bars are hinged or pivotedtogether at their adjoining ends, so that the holder may be opened, asshown in Fig. 12, to receive the sack to hold it open while the sack isbeing filled, and again open to discharge the sack after it has beensewed, and so that the holder may be closed, as shown in Fig. 13, tohold the mouth of the sack closed while it is being sewed.

To automatically open the holder, it is provided with one ormore,preferablytwo,springs cl at two of its pivots or hinges.

To adapt the holder to properly and firmly grasp the mouth edge of thebag, so that the bag and its contents may be securely supported from andcarried by the holder without any separate carrier for the bag, and toenable the sacks to be quickly and convenientlyinserted in the holder,the holder is provided at its two opposite pivotal ends with pivotedspring-actuated clamping-jaws d d, and at its two long or side bars dwith springactuated clamping-jaws cl d. The pivoted clampin g-j aw d isprovided with a pin or proj ection d adapted to engage a stationary camor projection 12 on one of the bridges 13 over the track 13, and thusautomatically open the clamping-jaw (1 when it passes under the bridgeand shown in Fig. let; and the clamping-jaw d is further provided with apivotal pawl or latch d to hold the clamping-jaw (Z open against thepressure of the spring cl of the clamping-jaw after the clamping-jaw hasbeen opened. A spring (2 holds the latch or pawl d in position forautomatically engaging the pivoted jaw (1 when said jaw is opened. Theclamping-jaw (1 consists, preferably, of a long sectional blade, that isto say, a blade having notches (Z at intervals. It is secured to arock-shaft (Z which is provided with a torsion'spring (Z to hold theclamping-jaw closed with the requisite pressure. The rockshaft 61 isfurnished with an arm or projection d, adapted to engage a cam orprojection 12 on one of the bridges B over the track B, and thus openthe clamping-j aw d as the holder passes under said bridge. Toautomatically hold the clamping-j aw d in its open position after it hasthus been opened, a pivoted pawl or latch al is provided, which ongagesa notch or projection cl on the clamping-jaw d, and thus holds the sameopen. The pawl or latch (Z is held in position for engaging the notch orprojection (Z by a spring (Z To put a bag in this holder, the holderbeing of course open, the operator first puts the edge of the bag underone of the end clamping-jaws d then touches the latch or pawl d, andthus clamps the mouth of the bag at one point to one end of the holder.He

then takes the diametrically opposite edge of the bag and in like mannerclamps it at the opposite end of the holder by the other end clamp d Hethen places one side edge of the mouth of the bag under one of the longclamps cl, releases the latch d, and thus secures this side edge of thebag in the holder. He then in like manner secures the other side edge ofthe bag under the other side clamp (Z By this means, and in this way,the bags may be placed in the holders with great rapidity. To increasethe holding power of the clamps d d and enable them to better supportthe weight of the filled bag, the clamping-faces are preferably providedwith serrations d.

The filling and measuring device E may be of any suitable constructionknown to those skilled in the art, and adapted to deliver a fixed ormeasured quantity of material into each bag, whether the measuring isdone by weight or by bulk. The device for this purpose illustrated inthe drawings iscon struct-ed to measure by bulk instead of by weight,and comprises a measuring-chamber E equal in capacity to that of thebag, a discharge-spout E delivery-spout E two valves E E anoperating-lever E the upper valve closing completely before the lowerone begins to open. The bag-shakin g device F,which operates to settleand compact the material in the bag as it is being filled, consists ofor comprises a movable section of the bag-holder track B,adapted to beautomatically vibrated up and down. This up-and-down vibrating movementmay be communicated to the bag-holder-shaking device F by any suitablemeans or mechanism, but preferably, as illustrated in the drawings, byrevolving cams or eccentrics f f on the shafts f, connected with thesectional track or device F by straps or hangers f After the sack hasbeen filled and duly shaken the holder D is moved along the track B bythe supplemental conveyer G into position opposite thesack-holder-elosin g slide or device G, and opposite the printing deviceH, the printing device being preferably arranged directly opposite theclosing device G.

The sack-holder-closing device G preferably consists of atransversely-reciprocating slide furnished with antifriction-rollers gto bear against one of the long bars (1 of the holder. The slide G orits stem g reciprocates in suitable guides g on the frame of themachine.

The printing or stamping device II may be of any suitable constructionknown to those skilled in the art. That, however, which I prefer toemploy is illustrated in the drawings, and comprises a reciprocating andrevolving or reversible type-carrying head 72 in which the type 7b aremounted, the head being pivoted to a reciprocating slide 7L2, workingback and forth in the frame 7F, and the rocking head being provided withcam-forks h adapted to engage pins 771 on the frame h and thus halfrevolve or reverse the type-carryin g head as it reciprocates, so thatwhen the head reciprocates backward the face of the type will engage theinking-pad h, and when the head reciprocates forward the face of thetype will be turned into proper position for engaging and stamping thesack. This is an old and familiar kind of printing and stamping device,and is shown in the drawings for convenience, although it will beobvious to those skilled in the art that other suitable or known formsof printing devices may be used in the place of that shown. Thereciprocating slide of the printing device is operated, or preferablyoperated, by the same lever G which actuates the bag-holder-closingdevice G, this being done by connecting the lever H which operates theslide of the printing device with the lever G by a link H Theprinter-operating lever H is a bent lever, and is provided at its upperend with a pivoted springheld arm H having a roller H to engage theslide 72. of the printing device and push it forward. To permit theprinting-head and its slide to be quickly withdrawn and thus preventblurring of the impression, the slide 7L is automatically withdrawn bysprings 7L7, the roller-carrying spring-held arm I-l being adapted topass under the slide the moment the impression is made. As the arm H ispivoted to the lever H, this permits the lever to be swung back intoposition at the rear of the slide 7L2 to repeat the operation on thenext bag. The spring H returns the pivoted arm 11 to position after itpasses out from beneath the slide 7L2.

. The bag-holder-closing slide G is reciprocated by the treadle or leverG through the intermediate bent lever G and connectinglinks G G, theconnecting-link G being provided with a spring G to retract the slide Gand lever G, and also the printer-operating lever 11. A spring hook orpawl 9 engaging the lever G, serves to hold the slide G closed until theholder passes.

The sewing device K may be of any suit able construction, but prefercbly comprises, as shown in the drawings, a frame arm or bracket K,attached to the frame of the machine, a reciprocating needle K a continuously-revolving looper K and suitable means for reciprocating the needleand revolving the looper. This operating mechanism may be, as shown inthe drawings, an upright shaft K, carrying a gear K which is providedwith a crank-pin K, connected to a pitman K which is connected at itsother end to a crankarm K on a crank-shaft K This crank-shaft K hasanother arm K which is connected by a pivoted link K to the slide or barK to which the needle is attached, and for operating the looper theupright shaft K is provided with a gear K which meshes with anintermediate gear K that meshes with a gear K? 011 the revolving shaft Kof the looper. r

The thread-cutting device or mechanism L consists of two reciprocatingknives, andthe thread-holding device L consists of two .re

ciprocating jaws between which the severed end of the thread is clampedor held after being severed by the knives. The two knives L L .and thetwo thread-holding jaws L L are preferably, one of each pair, connectedto the same reciprocating spring-actuated slide L Each of the slidingjaws L is furnished with a pin or roller L projecting in the path of theholder in the track 13, so that the instant each holder passes theprojection L the sliding bars L L carrying the knives and thread-holdingjaws, will be actuated or closed against each other by their springs L Land thus automatically sever the thread and grasp or hold the free endthereof.

The device M for autom atically dischargin or delivering the filled andsewed sack from the machine consists, preferably, of an i11- clined,revolving, spring-supported platform, so that, when the filled bag dropsonto it, it will by the weight and impulse of the bag automatically beswung around and thus discharge or deliver the bag out of the way. Thisinclined and revolving platform M is adapted to rock or rotate and alsoreciprocate up and down on a stationary inclined shaft M, and issupported by a spring M which bears at one end against a collar M fixedto the shaft M, and the other end against a sleeve M to which theplatform M is connected by rods M. The spring also acts torsionally,being connected at one end to the sleeve and at the other to the collar,and thus serves to automatically return the platform to position afterswinging outward to discharge a sack. An arm M, secured to one of therods M serves by striking against a brace of the frame to limit thetorsionally-inward throw of the spring.

N is the main driving-shaft of the machine, and N is the driving-pulley.Motion may be communicated from the driving-shaft N to the shaft 0 whichcarries the sprocket-wheel 0 that drives the endless conveyor-chain G byany suitable means or mechanism; but it is preferably done, asillustrated in the drawings, by a gear 02, on the shaft N meshing with agear 7?. on the short shaft if, said short shaft having a sprocket-wheeln" which communicates motion by a chain a to the sprocket-wheel n on acounter-shaft a, which counter-shaft carries a gearn meshing with thegear a on the short shaft a, which is provided with a bevel-gear 71 thatmeshes with a bevel-gear n on the shaft C to which said sprocket-wheel Cis secured.

Motion may be communicated to the supplemental carrier-chain C by anysuitable means or mechanism, but preferably, as illustrated in thedrawings, by providing the shaft it with a sprocket-wheel 02 whichcommunicates motion by a chain 01 to a sprocketwheel 11 on a shaft n, towhich the drivingpulley O of the supplemental carrier 0 is secured.

Motion may be communicated to the shaft f, which actuates the shaker F,by any suitable means, but preferably, as illustrated in the drawings,by providing the shaft n with a sprocket-wheel n, by which motion iscommunicated through a chain it to a sprocketwheel n on a clutch-sleevef loose on the shaft f, said clutch-sleeve being engaged by an opposingclutch-sleeve f which rotates with the shaft f, so that when theoperator by means of the clutch-rod f pulls the clutchsleeve f intoengagement with the clutch.- sleeve f the shaft f will be rotated. Itshould here be observed that the pulley or wheel 0 of the supplementalcarrier-chain O, which is on this shaft f, is a loose or idle pulley onthe shaft, so that the carrier-chain O can receive no motion from theshaft f, but only from its driving-shaft n as before explained. Theother shaker-operating shaft f is actuated from its companion shaft f bymeans of a chain f engaging sprocket-wheels f f on said shafts f f.

Motion may be communicated to the sewing device or mechanism or to theupright shaft K thereof by any suitable means, but preferably, asillustrated in the drawings, by a bevel-gear K on said shaft K whichmeshes with a bevel-gear P on a clutch-sleeve P which is thrown intogear with the drivingshaft N by a sliding clutch P said sliding clutch Pbeing automatically operated by a sliding arm 2), projecting into thetrack B in the path of the bag-holder D, and which sliding harp isprovided with an arm 1), that e11- gages the sliding clutch P which thusthrows it into engagement with the clutch-sleeve P A spring 19 serves toretract the clutch and throw the sewing-machine out of gear when thesewing of the bag is completed and the bag-holder D is carried past suchclutch-operatin g arm 1).

The operation is as follows: At the station- X, where the conveyer-chainO is out of engagement with the holders D, the bags are placed in theholders one after another by the operator. After the operator has put abag into one of the holders he pushes the holder forward along the trackB to the point where its hook (Z will engage the conveyer-chain. Theconveyer-chain then carries the holder along the endless track B to thepoint where the conveyer-chain G is deflected away from the track B, atwhich point the conveyerchain is automatically disengaged from theholder, thus leaving the holder stationary on the track B at or near thefilling-station. The operator at the filling-station then pushes theholder forward under the spout of the filling and measuring device. Theoperator then moves the valve-operating lever of the filling mechanismso that the material then runs into the sack or bag from the measuringchamber. The holder is now resting on the shaker F, on the up-and-downmovable portion of the track B, and the operator now moves theclutch-operating rod,which sets the shaker F into vibration. After thesack is sufficiently shaken the operator throws the IIO shaker out ofgear and with his hand liftsthe pivoted hook d on the holder D intoengagement with the supplemental carrier-chain O, and the holder withthe filled bag is thereby moved forward into position opposite thesack-holder-closing device G and the printing device H; the hook (1being automatically disengaged from the supplemental carrierchain 0 atthe point where said carrier-chain turns upward or around its pulley orsprocketdle or lever G actuates the closure-slide G and closes theholder, and at the same time actuates the printer-slide and thus stampsthe necessary impressions or marks upon the bag. The holder D is nowagain brought into engagement with the endless conveyer O, a d is by itconveyed past the sewing device K, the operatin g-clutch of which isthrown i to gear by the engagement of the holder with the projecting arm1:), which operates the clutch; and as the holder passes the threadcutting and holding device L L the thread is automatically severed andits free end ra d and held. As the holder passes along the endless trackthe arms d and d engage th cams or projections b b on the bridges B Band thus automatically release the clampingjaws d 01 thus permitting thebag to drop out of the holder down upon the discharger M; and at thesame time. the springs d on the holder throw the holder open, as it hasnow reached the point where the guide-fiange h of the track B is widelyseparated from the carrier C, so that the springs d can throw the holderopen. It should also be observed that when the clamping-jaws d d areautomatically thrown open by passing under the bridges B B they arelocked or held in thisopen po sition by the latches or pawls 01 (Z untilthese latches or pawls are again released by the operator when he putsanother bag into the holder. The conveyer O carries the holder back tothe station where the bags are inserted, when the operation is repeatedsue-- cessively with each and all of the holders of the series. WVhenthe holder D is closed by the slide G,

, the short bars 61 are brought into line with the long bars CF, andthis act of closing the holder thus throws the hook 01 on the frontshort bar 61 adjacent to the conveyer-chain 0, into engagement with theconveyer-chain, so that the moment the holder is closed by the slide Git will be caught by. the chain 0 and carried forward along the track Bpast The holder'closin g slide G holds the holder closed by reason ofthe spring pawl or hook g until the holder is advanced by the conveyer Ginto the contracted part of the track B, where the flanges Z; 1)converge to the width of the holder when it is closed, so that saidflanges of the track will then keep the holder closed.
